When the bucket tooth is fixed to the bucket body, one end of the limiting block is located outside the bucket tooth and is inserted into the bucket body.

[0009] By adopting the above technical scheme, when a new bucket tooth is replaced, the limiting block is completely inserted into the bucket tooth through the driving member. At this time, one end of the bucket tooth close to the limiting block is inserted into the bucket body. The limiting block is driven by the driving member to move away from the bucket tooth until the limiting block is inserted into the bucket body, so that the bucket tooth is fixed to the bucket body, the stability of the installation of the bucket tooth is improved, the bucket tooth can be conveniently disassembled and replaced, and the replacement cost of the bucket is reduced.

[0016] Optionally, the fixing assembly comprises two plug blocks symmetrically and fixedly connected to two ends inside the mounting shell, the bucket body is provided with a plug slot corresponding to the plug block at each end, and the plug block is plugged into the corresponding plug slot.

[0017] By plugging the plug block into the corresponding plug slot and fixing the mounting shell and the bucket body through the fixing member, the plug block increases the contact area of the mounting shell and the bucket body, thereby improving the stability of the connection between the mounting shell and the bucket body.

[0018] Optionally, the fixing member comprises two second screws symmetrically arranged at two ends of the mounting shell and parallel to the length direction of the bucket body, one end of each second screw is arranged to pass through the side wall of the mounting shell and the plug block and be screwed with the bucket body, and the second screws are screwed with the mounting shell.

[0019] By plugging the plug block into the corresponding plug slot and driving the second screws to move and rotate in the direction close to the bucket body until the one end of each second screw is screwed with the bucket body, the mounting shell is fixed on the bucket body, and the stability of the connection between the mounting shell and the bucket body is further improved.

[0020] Optionally, the width of the plug block gradually increases towards the side close to the bucket body.

[0021] By adopting the above technical solution, the shape of the plug block limits the mounting shell in the height and length directions of the mounting shell when the plug block is plugged into the plug slot, thereby reducing the possibility of the mounting shell from the bucket body under the action of external force and further improving the stability of the connection between the mounting shell and the bucket body.
